It was a real-life “Rumble in The Bronx” Sunday as two men faced off in a movie-style sword fight at the door to an apartment building — with one brandishing a foot-long blade and another a heavy metal rod.

The broad-daylight drama started at about 11 a.m. at 1275 Edward L. Grant Highway in Highbridge when a man with an iron bar and no shirt came knocking.

It’s not clear why he was there, as there was no police report made of the brief encounter.

But the bar-wielding aggressor was greeted at the door by a rude surprise: a man gripping what looked like a small samurai-style sword.

The shirtless man was not deterred, crouching into a defensive position as he waved his crude club.

The sword-carrying man, meanwhile, used the door like a shield as both combatants swung at each other during the fight, which lasted about 15 minutes.

It wasn’t clear to witnesses what the fight was about, but the shirtless man scampered off after he was cut on the arm. Witnesses said he vowed to return.
